Here are a couple comments on the progression of the slides:
1: Intro - good
2: Blank - placeholder - you'll fix this
3: The Problem - good. Maybe say that *loss* only provides binary signal per RTT -> Oscillation -> Bang-bang control theory
Then... swap slides 4 & 5
4: Two Congestion Signals - major bullet points
- Congestion should be an earlier signal than loss
- Swap CE & SCE, noting CE gives coarse info
- We propose SCE, to give high fidelity information
5: Rename heading - s/The Solution/The Implementation/
6: State Diagram - good
7: Experimental Plan - good
8: Plot - You need to have an explanation of the graph on the final slide. It's a bit hard to read the axes, but way more important is a clear description of what the heck we're looking at. It won't be as detailed as [Explaining RRUL Charts](https://www.bufferbloat.net/projects/bloat/wiki/RRUL_Chart_Explanation/) but someone reading (only) the slides should be able to understand what the plot shows.
9: Some kind of summary
Good luck!
Rich

That's also true of CE, because of the feedback mechanism which involves making ECE sticky for an RTT. I'm sure that was part of making sure CE was equivalent to loss.

OK. I haven't been following this discussion carefully, so am happy to be corrected.
I would still swap slides 3 & 4 (introduce the new idea before telling people that you're taking over ECT(1))
The plot is (much) better now but could benefit from a narrative. Perhaps the chart could be smaller (since it's much more readable) with a legend on the right to describe what the colors show. (I know you'll say it in the presentation, but a reader won't know what this is about.)
Thanks again!
Rich
PS - And how many minutes do you have left before presenting? :-) Good luck, and have fun!

Why can't you divide amount-of-missing by (RTT * goodput), for
a proportional signal? Only one sample of signal per RTT, but
better than binary.
